Pepco has purchased the University of Maryland's winning entry of the Solar Decathlon for $200,000, and plans to reassemble the environmentally conscious home on one of its properties to use as an educational site.

The university's entry, called "Watershed," is a solar-powered home inspired by the Chesapeake Bay that took the top prize in the U.S. Department of Energy's contest last fall. It features a green roof that provides insulation and a system that filters sink and shower water, recycling it for use in wetland gardens built along the length of the house.
